Abstract
Objective
To investigate the role of lncRNA Snhg6 in liver fibrosis, delivered by resveratrol-stimulated macrophage exosomes.
Methods
Resveratrol-stimulated and unstimulated exosomes were generated from RAW 264.7 cells, confirmed by electron microscopy, nanoparticle analysis, and Western blotting. JS1 cells were used as an HSC model, activated with TGF-β1 and treated with exosomes. Exosome uptake was observed via confocal microscopy, and acta2 expression was measured with immunofluorescence. RNA sequencing and RT-qPCR were used to analyze exosomal lncRNA profiles. KEGG GSEA enrichment was conducted on differentially expressed genes, and nf-κb expression was detected in HSCs using WB. Serum from liver fibrosis patients was analyzed for SNHG6 levels.
Results
Resveratrol-stimulated exosomes inhibited TGF-β1-induced HSC activation, with 132 differentially expressed lncRNAs, including upregulated Snhg6. NF-κB signaling was downregulated. Silencing Snhg6 weakened this inhibitory effect.
Conclusion
Resveratrol-stimulated macrophage exosomes may inhibit liver fibrosis by delivering lncRNA Snhg6, which suppresses the NF-κB pathway.
